The closest thing to "signs of life" that's been found on Mars so far has been marks on the topography
believed to have been carved by liquid water at some time in the distant past.
No living organisms, or their carcasses, or their effluent, have been detected in the Martian soil, and
no giraffes have yet pranced through the view of any camera carried by a Mars probe.
Well it depends on what you mean if you mean life they found signs showing that there used to be life on mars but not any actual creatures living there if you mean anything else they bound a barren planet of desert with signs showing that there used to be little streams there.
The current US Mars probe is called Perseverance. It landed on Mars in February 2021 with the primary goal of searching for signs of past microbial life and collecting samples for future return to Earth.
COULD Mars have life? Yes, it could. We see life in some very inhospitable places on Earth, such as in deep caves, volcanic fumaroles at the bottom of the sea, and ice-covered lakes in Antarctica. DOES Mars have life? It seems unlikely; several robot probes including three rovers have detected no signs of it. But every probe continues to look for clues as to if Mars has, or ever did have, life.

As of now, there is no definitive evidence of life on Mars found by astrologists. Various missions to Mars, such as the Mars rover missions by NASA, have searched for signs of past microbial life but have not yet confirmed its existence. The search for life on Mars is ongoing with future missions planned to further investigate the possibility.
The space probe found ice caps that prove that running water at one time flowed on Mars. Investigations continue to find any form of life that could have inhabited these waters.
at the moment, there are no signs of life. There could be but most like there isnt. If there are Martians on Mars, they would be natives.
It has yet to be determined, some of the probes that NASA has sent to Mars is in search of life and the one that they are planning to send up in 2011 should give us a good answer. The probe will be looking for signs of life and will be in search of microbes. If microbes are found on Mars then yes there really are Marshans but nothing of the intelligent life were are used to seeing in Hollywood.
There MIGHT be life in on some of the larger moons; or even in outer space.
In 1976 twin Viking spacecraft reached Mars. Each of the Viking landers carried a small laboratory meant to search for life forms. These laboratories tested Mars's air and soil for signs of life. None of these test showed evidence of life.
The topic of life on Mars has been one of hot debate lately with the recent Rover bot finding more "possible" signs of life on Mars. However, there is no definitive evidence that there is life on Mars.
The robot will search for signs of life on Mars.
